DC Distribution and Protection Components
Introduction
Photovoltaic systems are composed by photovoltaic panels, cables, fuses, switches, overvoltage arresters and power
inverter. Photovoltaic panels utilise the power of sun light to converters photons to DC current.
Electricity generated by solar panels is then fed into a power inverter that converts DC current to AC current. gPV fuse
has been developed to protect cable and panel against "reverse" overcurrent.
ETITEC B, C-PV series of over voltage surge protective devices has been developed to protect against direct and indirect
lightning discharges and is intended to protect photovoltaic systems.
The circuit topology consists of two varistors stages each protected by a thermal disconnection device.
Overcurrent protection
PV module protection from »DC REVERSE« current on DC side
Array with three or more strings of panels:
PV systems that have three or more strings connected in parallel need to have each string protected by fuses.
Systems that have less than three strings will not generate enought fault current to damage the conductors/solar
panels.
Normaly there are two gPV fuses connected on each string (+ and - pole), that protect conductors/solar panels from
damage and eliminate any safety hazards.
Fuses isolate the faulted string. The rest of PV system can continue to generate electricity.
PV module protection from »AC REVERSE« current caused by defective inverter
If an inverter becomes defective (transformerless…), AC reverse current can feed into DC strings and destroy PV modules.
